That picture doesn't prove anything.. I can take the exact same picture..I don't see why neimod's upside-down screen is so impressive.
Did you mean to put sarcasm brackets on the sentence?
The upside-down screen is impressive because he finally made a RAM dumper that works on the 3DS (apparently it has sort of a protection, and if I remember right it has a special nand chip which isn't easy to desolder/resolder), meaning he could potentially get the private keys so software/channel hacking could be possible. He *might* be able to finish informing the scene how saves work as well by viewing what the 3DS is doing behind the scenes, so save file modding *might* become possible. Of course, this would take him some time to do it by himself.
Look at his other pictures, he shows the RAM board he built. He's proven himself in the past with a similar DSi hookup in case you haven't heard of him.
